In a rope-climbing competition, all of the lifting is done by the arms; legs can only dangle. Imagine 220-lb Garvin Smith in training, hanging stationary from the rope, his legs off the floor. When prompted by his coach, he rapidly lifts his center of mass by 4 ft. in 0.65 s. Calculate Garvin Smith's acceleration. Round the final answer to one decimal place. Determine the net force (“force imbalance”) producing the acceleration. Round the final answer to one decimal place. Which forces are acting on Smith? (Note that his arms are part of himself, so they cannot exert a force on Smith.) With what magnitude force is Smith pulling down on the rope? Round the final answer to one decimal place. The force of 130.2 lb points _____.

A grave digger digs a grave with a varying force F equals 10 plus s squared Newtons, where s is in millimeters. The resulting force of the shovel is at about 30 degrees away from the tangent line from the curved motion path of the shovel. If he already shoved dirt at a curve's displacement of 150 millimeters per shove, and he did about 158 shove counts already, determine the grave digger's work done in kilocalories. 300

A tugboat with a displacement¹ of 50 tonnes and resistance² of 750 kN is towing a 75-tonne barge with resistance of 1000 kN. The tugboat has a propeller generates thrust³ of 7 to move it forward, while the barge is non-propelled. Determine the thrust and the force exerted by the rope on the tugboat, given that it takes 35 seconds for the tugboat to uniformly increase its speed to 13.5 knots4. ces: 1. The displacement or displacement tonnage of a ship is its weight. It refers to the weight or mass of water that a ship displaces when it is floating in water. 2. Ship resistance, also known as hydrodynamic resistance, refers to the force that opposes the motion of a ship or vessel as it moves through water. 3. The thrust of a propeller refers to the force generated by a rotating propeller that propels a vessel through water. 4. Knot is a unit of speed used to measure the speed of a vessel. One knot is equal to 0.5144 m/s. 2: OO TT
